You don't have any sched_fifo_high() ? Thanks! and no. I'll go write a Changelog and add it to tip/sched/fifo, so that hopefully, sfr can stop complaining about this build fail ;-) I've even argued we should rename fifo_low() to something else, but failed to come up with a sensible name. The intended case is for when you want something above normal but don't particularly care about RT at all. The thing is, once you start adding priorities, even low,med,high, we're back to where we were. And the whole argument is that the kernel cannot set priorities in any sensible fashion.
